Navigation

A 3d surface can be manipulated in three dimensions, making navigation significantly more complicated than on a 2d map. In additional to simple zoom and pan, a 3d surface can be rotated in multiple axes.

Maptitude surfaces can be moved and rotated using either the navigation control that appears in the top right of the surface display window, or by using the top eight buttons of the 3d Toolbox. The surface display window’s navigation control looks like this:

The 3d Toolbox is displayed from the Surface Analysis sub-menu (here show in a 2-column format):

The 3d Toolbox

The navigation controls are dragged in situ. The 3d Toolbox buttons set the navigation mode which you then use to drag the surface with the mouse.

To pan the surface, select the ‘hand’ (pan) button, or press one of the eight triangles on the outside of the navigation control’s compass rose. You can also pan by clicking on the central star in the compass rose, and dragging the mouse in the desired direction.

To zoom the surface, select the ‘up red arrow’ (zoom) button, or drag the vertical slider on the right of the navigation control.

To rotate the surface around the vertical axis (i.e. through the different compass directions), select the ‘circular rotate’ button, or drag the small triangle in the inner circle of the compass rose. This small triangle indicates the current direction of north.

Finally to tilt the surface up (towards the viewer) or down, select ‘horizontal rotate’ (tilt) button or use the horizontal slider along the top of the navigation control.

The remaining navigation buttons on the 3d Toolbox are used to return back to the original view, or to set a ‘view bookmark’. It can be time-consuming finding an ideal viewpoint, so it is often useful to set a ”view bookmark” to make it easy to return to a previous view. Create a bookmark by pressing the button with the red flag and a magnifying glass.
